Most Mysterious Unsolved Disappearances
Some cases get solved. A witness comes forward, a piece of evidence surfaces, a confession breaks years of silence.
But then there are the others — the ones where no amount of searching, theorising, or investigating has produced a single solid answer. These are the disappearances that refuse to close.
The people who simply stopped being somewhere, with no clear explanation for how or why. What follows are some of the most baffling vanishings in recorded history, spanning centuries and continents, and still without resolution.
Amelia Earhart
In July 1937, aviation pioneer Amelia Earhart and her navigator Fred Noonan disappeared somewhere over the Pacific Ocean during an attempt to circumnavigate the globe. They had already completed more than two-thirds of the journey when radio contact was lost near Howland Island.
A massive search effort found nothing. Earhart was officially declared dead in 1939.
Decades of expeditions have produced fragments of bone, aircraft parts, and competing theories, but nothing conclusive. Some researchers believe she crashed into the ocean.
Others think she landed on a remote island and died as a castaway. A few fringe theories go further.
After nearly nine decades, the question of what happened to her remains genuinely open.
The Roanoke Colony
In the late 1580s, more than a hundred English settlers established a colony on Roanoke Island, off the coast of what is now North Carolina. The colony’s governor, John White, sailed back to England to collect supplies.
When he returned in 1590, every single person was gone. No bodies, no signs of violence, no indication of where they had gone.
The only clues left behind were the word “CROATOAN” carved into a fencepost and “CRO” cut into a tree. Croatoan was the name of a nearby Native American tribe and the island they inhabited.
Whether the settlers joined them, were absorbed into the tribe, or met some other fate entirely has never been established. Archaeological work in the region continues, but a definitive answer has never emerged.
D.B. Cooper
On November 24, 1971, a man using the alias Dan Cooper boarded a flight in Portland, Oregon, handed a flight attendant a note claiming he had a bomb, and demanded $200,000 in ransom and four parachutes. The airline complied.
After the plane landed and the passengers were released, Cooper ordered the crew to fly toward Mexico at low altitude. Somewhere over the Pacific Northwest, he strapped on a parachute and jumped into the night.
He was never found. A small bundle of the ransom bills turned up along a riverbank in 1980, but that discovery raised more questions than it answered.
The FBI investigated the case for 45 years before officially suspending active investigation in 2016. No confirmed identity for D.B. Cooper has never been established, and no one knows whether he survived the jump.
Jimmy Hoffa
Jimmy Hoffa ran the Teamsters union, one of the most powerful labour organisations in the United States, and his dealings with organised crime were an open secret. After a stint in federal prison for jury tampering and fraud, he was released in 1971.
On July 30, 1975, he went to a restaurant in suburban Detroit to meet with Mafia leaders. He was never seen again and was legally declared presumed dead in 1982.
The theories about what happened to Hoffa, and where his remains ended up, have been plentiful. Under a stadium.
Encased in concrete. Buried in a field in New Jersey.
Investigators have dug up multiple sites over the years, each time finding nothing. More than five decades on, the case remains one of the FBI’s most enduring organised crime investigations — and one of its most frustrating.
Malaysia Airlines Flight MH370
On March 8, 2014, a commercial passenger aircraft carrying 239 people took off from Kuala Lumpur bound for Beijing. At some point during the flight, the plane deviated from its course, turned around, and flew for hours in a completely different direction before dropping off radar entirely.
No wreckage appeared for over a year. When debris finally began washing up on remote coastlines, it confirmed the plane had gone down in the southern Indian Ocean — but explained nothing about why.
The question of what happened on board MH370 has never been answered. Whether it was mechanical failure, a deliberate act by someone in the cockpit, or something else entirely is unknown.
Most of the aircraft, and all 239 people on board, have never been found. It remains the biggest aviation mystery of the modern era.
Madeleine McCann
In May 2007, three-year-old Madeleine McCann vanished from a holiday apartment in Praia da Luz, Portugal, while her parents dined at a nearby restaurant. When they returned to check on the children, she was gone.
The window was open. The door was unlocked.
The case triggered one of the largest missing persons investigations in European history. It has never been solved.
Madeleine has never been found. A German suspect was identified by investigators in 2020, but no charges have been laid in connection with her disappearance.
Her parents have never stopped searching.
Ambrose Bierce
Ambrose Bierce was one of America’s most celebrated writers by the time he decided, at the age of 71, to travel to Mexico in 1913 to observe the revolution led by Pancho Villa. He sent a few letters from the front lines, describing the fighting in typically vivid terms.
Then the letters stopped. Nobody knows what happened to him.
Some believe he was killed in battle during the siege of Ojinaga. Others have theorised that he took his own life, or that he simply never went to Mexico at all.
Nobody was ever recovered, no grave identified, no official record of his death found. He stepped into a conflict and never stepped out.
The Mary Celeste
In December 1872, a Canadian brigantine called the Dei Gratia came across an American merchant vessel drifting in the Atlantic Ocean. The ship was the Mary Celeste, and she was completely deserted.
The cargo was intact. Most of the crew’s personal belongings were still on board.
There was no sign of a major struggle. But the lifeboat was gone, one sail was missing, and the last log entry was dated November 25 — ten days earlier.
What happened to the ten people on board has never been explained. The theory floated at the initial Gibraltar inquiry — that the crew drank the cargo of industrial alcohol, murdered the captain, and fled — was never proven.
Piracy, water spouts, seaquakes, paranoia, and mutiny have all been suggested over the years. None of the crew was ever found.
Benjamin Bathurst
In November 1809, a British diplomat named Benjamin Bathurst stopped at an inn in the small Prussian town of Perleberg while travelling home from Vienna. He had been on a mission to persuade Austria to ally with Britain against Napoleon.
Witnesses at the inn noted that he seemed nervous and had asked a local official for armed protection. After dinner, Bathurst went outside to inspect the horses.
He walked around to the other side of the carriage. And vanished.
An extensive search found nothing. A skull later turned up in a house linked to someone who had worked at the inn during the time of his disappearance, but it was never conclusively identified as Bathurst’s.
Whether he was robbed and murdered, abducted by French agents, or met some other end is still unknown.
Brian Shaffer
On the night of April 1, 2006, a 27-year-old medical student named Brian Shaffer went out with friends to a bar in Columbus, Ohio. Security footage showed him entering the Ugly Tuna Saloona.
It never showed him leaving. Every exit was captured on camera.
Brian simply did not appear on any of them. No trace of him has ever been found.
Nobody, no confirmed sightings, no clear explanation for how he left a building that was being recorded on all sides. The case has been investigated repeatedly without resolution.
His father spent years searching before his own death, still without answers.
Richey Edwards
Richey Edwards was the rhythm guitarist and lyricist for Welsh rock band Manic Street Preachers. In February 1995, two weeks before the band was scheduled to fly to the United States for a promotional tour, he disappeared from a London hotel.
His car was later found near a bridge over the Severn Estuary known as a site for people who had chosen to end their lives. Nobody was ever found.
No credible confirmed sighting emerged. He was officially declared presumed dead in 2008.
Some of his fans have never fully accepted that conclusion. Over the years, alleged sightings have come in from as far away as Goa.
Whether he died near that bridge or chose to disappear entirely and start a different life remains unknown.
The Bennington Triangle
Between 1945 and 1950, at least five people disappeared in a small area of southwestern Vermont near Glastenbury Mountain. The victims included a young woman who vanished from a hiking trail, a man who disappeared from a crowded bus while passengers slept, a farmer who walked out of his house and never came back, and others.
No bodies were recovered in most of the cases. No explanations were ever found.
The area has since been nicknamed the Bennington Triangle, a name borrowed from the more famous Bermuda Triangle. Theories range from a local serial killer to something far harder to define.
The cases have no obvious connection to one another beyond geography and timing, which is part of what makes them so difficult to dismiss.
Frederick Valentich
On October 21, 1978, a 20-year-old Australian pilot named Frederick Valentich took off in a small Cessna aircraft over the Bass Strait between mainland Australia and Tasmania. During the flight, he radioed air traffic control to report an unidentified aircraft flying above him and performing manoeuvres he couldn’t explain.
He described it in detail, growing increasingly distressed. The radio then picked up a strange metallic scraping sound.
After that, silence. Valentich, his plane, and whatever he had been watching in the sky above him were never found.
The Australian Department of Transport concluded that the reason for the disappearance could not be determined. His case remains one of the most discussed and least resolved aviation mysteries in the country’s history.
Owen Parfitt
In the summer of 1763, a paralysed man in his sixties named Owen Parfitt was sitting on the front porch of his sister’s home in the English village of Shepton Mallet. Farm workers in a field across the road were within clear line of sight. His sister stepped inside for a moment.
When she came back, he was gone. For a man who could barely move on his own, disappearing without anyone noticing was essentially impossible.
The farm workers saw nobody approach and nobody leave. Parfitt was never found.
The case sat largely forgotten for generations before historians rediscovered it. It remains one of the oldest truly inexplicable disappearances on record.
The Weight of Not Knowing
What happened to someone can be very hard for the people who loved them. The common feature of these cases is not only the absence of answers to what happened to these persons but more importantly how such absence keeps haunting the family members.
Even though missing person cases are usually closed after a certain period of time, media attention gradually disappears, the world moves on, and the families do not. There is always a question: someone was here and suddenly there was no one and no one can explain why.
Such a gap, i. e. the last moment when someone was known, and the endless time thereafter, is truly the living place of these stories. However, for most of them, it will be their lifelong residence.
